Comparison of water in two adjacent watersheds before and after implementing a brush management strategy in one of the watersheds helps us see what water resource characteristics are sensitive to brush management and how.

Changes in the way communities address potential problems with stormwater runoff may affect surface waters. This study combines geographic with hydrologic analyses to better understand the effects of the management strategies.

Cooperative national project with the Federal Highway Administration (FHWA) to evaluate FHWA's guidelines for highway-runoff quality. Links to searchable online bibliography of related publications by the USGS, EPA, FHWA, and state agencies.

Report on the hypothesis that variations of the total solar irradiance reaching the Earth and its atmosphere affect the precipitation and runoff of the western U.S. Includes links to research papers, bibliography, and climatic data.

Overview of a project to evaluate existing methods used by Virginia Dept. of Transportation to estimate flood hydrographs from small drainage basins, and evaluate the use of dimensionless hydrographs to estimate runoff volumes.

Stream discharge and nitrate concentration increased downstream of the burned area during snowmelt, but these were probably within the treatment capacity of most drinking-water plants, and limited changes were observed in downstream ecosystems.
